Mary, Queen of Scots, was betrothed to the Dauphin Francois, son of Henri II. He was a sickly and unpleasant little brat, but she apparently liked caring for people - after he died she was quite prepared to marry the idiot son of the King of Spain, and she only got personally interested in Lord Darnley later when he fell ill with measles. She was, however, held on ice, as it were, for thirteen years, in case a better bargain for the future Queen of France turned up. They were married just after Henry VIII died, when Mary could make a good claim to the throne of England in place of the formally illegitimate Elizabeth, who had to imprison most of the bishops in England before she could persuade one of them to crown her.
